Title
Study of elementary excitations of superfluid $^{4}He$ in silica aerogels
Author
Abstract
 We have studied the elementary excitations of superfluid He-4 in a silica aerogel at 1.8 K and various filling fractions. The results do not show any departure from bulk He-4 behaviour, suggesting that previously observed anomalies in heat capacity and superfluid fraction data could be the effect of a distribution of He I and He II liquids inside pores of different sizes.
